I think it really depends. I have seen a lot of teams / managers would prefer a so call team player to sit there and write 500 lines of bad code, and ditch a good coder who don't go to all the bullshit meeting for write 500 lines of good code. And the glory go to the 500 lines of bad code, for showing up in meetings and talk about shits. That's respect.

I would like to share one quite from Gandhi: Whatever you do will be insignificant, but it is very important that you do it.

People usually don't know what is a good idea / bad idea. Otherwise killer products can be made from market survey, but this is usually not the case.

I second the comment from switch. Also even you just got one user, you are still doing something for good. Start it small, just spend a week or so build a prototype and release it.
